SPECIFICATION forming part ofLetters Patent No. 739,715, dated September22, 1903.

Application filed March 28, 19Q3. Serial No. 150,018. (No model.)

1"0 (tZZ whom it inrtyconcernz Be it known that I, AMANDUS HOWELLRANDOLPH, a citizen of the United States, residing at Corry, in thecounty of Erie and State of Pennsylvania, have invented anew and usefulDumping-Wagon, of which the following is a specification.

My invention is an improvement in dumping apparatus, and while it isshown as applied to a wagon it is equally as well adapted for use withcars.

The object of the invention is to provide a double pivoted bottom andmeans fordumping the same, whereby the material may be dumped in thecenter ofthe road or track or at the sides of same. 7

My invention consists in a sectional bottom, the sections extendingthelength of the car or wagon and so pivoted at their ends that eachsection can be tipped in either direction.

The invention consists also in the special features of constructionpointed out in the claims and shown in the accompanying drawings, inwhich- Figure 1 is a side view of a wagon equipped with my dumpingapparatus. Fig. 2 is aplan view of Fig. 1. Fig. 8 is an end view showingthe dumping mechanism. Fig. 4 is asection about the line i i of Fig. 2.Fig. 5 is a detail view, partly in section, showing the bearing-plates.Fig. 6 is a perspective view showing from the under side an end of oneof the sections and the bracket by which it is secured to a revolubleshaft running the length of the vehicle.

In the drawings, A represents the sides of the body of a wheeledvehicle, the ends A of which preferably extend below the sides. Arrangedcentrally in the lower part of the body and extending from end to end isa ver ideally-arranged strip B, diamond-shaped in cross-section.Journaled in and extending through the end pieces and below the plane ofthe bottom of the body are two parallel shafts 0, each arranged midwaybetween one of the sides and the strip B. Adjacent the inner faces ofthe ends a bracket D is rigidly secured on each shaft, having armsextending laterally and slightly upwardly. The two bottom sections E aresupported by and secured to these brackets and have beveled side edges,as shown at E. On each end of each shaftare rigidly mounted gear-wheelsF. On the outer and inner faces of each end piece between the gears Fare arranged metal plates F, and journaled in these plates are gears Fof similar size and larger than the gears F. Each set of gears F meshtogether and also with the adjacent gear F. On one of the end pieces ismounted a quadrant F", above and meshing with one of the gears F A leverF is rigidly secured to the quadrant and slides between parallelsegments F bolted together but spaced apart, and a gripping-catch F ispivoted to the lever and engages notches cut into the outer segment. v

The operation of my device is as follows: When it is desired to dump thematerial to one side, the lever, which is normally in a verticalposition, is moved to the left, the gears and'shafts are rotated, andthe outer edges of the bottom sections are swung downward in thedirection of the lower arrows of Fig. .4. If, however, it is desired todump the material on the road or track, the lever is moved to the rightand the inner edges of the sections swing downward, the outer edgerising, as indicated by the upper arrows 0 Fig. 4. The positionsoccupied by thebottom sections when the lever is moved in each directionare shown in dotted lines in Fig. 4. 7 It will be noted that when in itsnormal position the center of each section E is slightly lower than thesides.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A dumping apparatus comprising two parallel bottom sections pivotedcentrally adjacent each end, and means common to each section fortipping them toward or away from each other.

2. The combination with a vehicle, of parallel shafts revolublyjournaled in the ends of the vehicle, brackets secured on said shafts, astationary strip running from end to end of .the vehicle between'theshafts, a bottom section carried by the brackets on each shaft, andmeans for rotating the shaft in either direction.

3. The combination with a vehicle, a strip extending centrally from endto end of the vehicle, shafts journaled in the ends on each and eachmeshing with a gear on one of the side of the stationary strip, andextending shafts, a quadrant engaging one of theinter- 10 through saidends, bottom sections rigidly mediate gears, and a lever adapted to moveconnected to and supported by said shafts, said quadrant in eitherdirection.
